Dissipative Dark Matter on FIRE: II. Observational signatures and constraints from local dwarf galaxies
We analyze the first set of cosmological baryonic zoom-in simulations of galaxies in dissipative self-interacting dark matter (dSIDM). The simulations utilize the FIRE-2 galaxy formation physics with
Formation of proto-globular cluster candidates in cosmological simulations of dwarf galaxies at $z>4$
We perform cosmological hydrodynamical simulations to study the formation of proto-globular cluster candidates in progenitors of present-day dwarf galaxies (Mvir ≈ 1010M at z = 0) as part of the
Extinguishing the FIRE: environmental quenching of satellite galaxies around Milky Way-mass hosts in simulations
The star formation and gas content of satellite galaxies around the Milky Way (MW) and Andromeda (M31) are depleted relative to more isolated galaxies in the Local Group (LG) at fixed stellar mass.
Public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
We describe a public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation, available at flathub.flatironinstitute.org/fire, from the Feedback In Realistic Environments (FIRE)
The Galaxy Progenitors of Stellar Streams around Milky Way–mass Galaxies in the FIRE Cosmological Simulations
Stellar streams record the accretion history of their host galaxy. We present a set of simulated streams from disrupted dwarf galaxies in 13 cosmological simulations of Milky Way (MW)–mass galaxies
New Families in our Solar Neighborhood: Applying Gaussian Mixture Models for Objective Classification of Structures in the Milky Way and in Simulations
The standard picture of galaxy formation motivates the decomposition of the Milky Way into 3–4 stellar populations with distinct kinematic and elemental abundance distributions: the thin disk, thick
Using Action Space Clustering to Constrain the Accretion History of Milky Way like Galaxies
In the currently favored cosmological paradigm galaxies form hierarchically through the accretion of numerous satellite galaxies. Since the satellites are much less massive than the host halo, they
The origin of metal-poor stars on prograde disc orbits in FIRE simulations of Milky Way-mass galaxies
In hierarchical structure formation, metal-poor stars in and around the Milky Way (MW) originate primarily from mergers of lower-mass galaxies. A common expectation is therefore that metal-poor stars
Planes of satellites around Milky Way/M31-mass galaxies in the FIRE simulations and comparisons with the Local Group
We examine the prevalence, longevity, and causes of planes of satellite dwarf galaxies, as observed in the Local Group. We use 14 Milky Way/Andromeda-(MW/M31) mass host galaxies from the Feedback
